This system makes Para's LDA models a joy to shoot. During rapid fire exercises, I have found that it is easy to bring the trigger back to its breaking point, quickly check the sights for alignment, and then add the extra pressure necessary to break the shot.
Added Safety
Szabo went to great lengths to make his LDA guns as safe as possible. The thumb safety is in the usual 1911 location, and Para uses an extended version that I like because I let my thumb ride atop it while shooting.
The safety is different on the LDA system than it is on standard 1911s. Rather than being a mechanical block to the sear, the LDA safety disconnects the trigger's drawbar when it is engaged. This means the trigger can be pulled, but the hammer won't move and the pistol won't fire. It also means that users will want to carry their LDAs loaded with a round in the chamber and the thumb safety engaged.
Para's beavertail grip safety, while in the same location as any ordinary 1911, performs the same function, in effect, but in a different way. On the Black Watch Companion, the beavertail locks the hammer, trigger, and slide. It's impossible to either pull the trigger and fire the gun or retract the slide to chamber a round unless the user depresses the grip safety.
